DANIEL C. COURTNEY, OF ALLEGI-IENY, PENNSYLVANI.

'l'FlUCK-BOLSTEIR.`

SPECIFICATION forming part of Letters Patent No. 748,167, dated December 29, 1903.

Y'lpplication filed October 15, 1903.

To all whom t may concern.-

Be it known that I, DANIEL C. COUETNEY, a citizen of the United States, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented new and use- `ful Improvementsin Truck-Bolsters,of which the following is a specification.

The objectof my invention is the production of a bolster for car-trucks which can be constructed in the ordinary car-shops without the use of special tools, which shall be strongand durable and especially adapted for the support of great weights without bending, so as not to allow the side bearings to come in contact with the side bearings upon the body-bolster, which shall be adapted for use with car-bodies' which are either relatively high or low from the track, and which withal shall constitute a superior means for performing the requisite functions.

With these ends in View my invention consists in certain novelties of construction and combinations of parts hereinafter set forth and claimed.

The accompanying drawings illustrate four examples of the physical embodiment of my invention constructed according to the best modes I have so far devised for the practical application of the principle.

Figures 1, 2, 3, 4, 5, 6, and 7 illustrate the first example. Fig. 1 is a top plan View. Fig. 2 is a side View in elevation. Fig. 3 illustrates one of the metallic beams which constitutes an element of the bolster, the anges and web being cut away in part as shown. Fig. 4 is an end View of Fig. 1. Fig.`5 illustrates a skeleton filling-piece removed. Fig. 6 is a top plan view of Fig. 5. Fig. 7 isa side View of Fig. 6. Figs. S, 9, 10,-11, 12, 13, and 14 illustrate the second example. Fig. 8 is a top plan view. Fig. 9 is a side View in elevation with part of one end broken away.

Fig. 10 illustrates one of the metallic beams with parts of the lower flange and web cut away. Fig. 11 is an end View of Fig. 8. Fig. 12 shows a skeleton filling-piece removed. Fig. 13 is a top plan View of Fig. 12. Fig. 14 is a side view of Fig. 13. Figs. 15, 16, 17, 18, 19, 20, and 21 illustrate the third example. Fig. 15 is a half top plan `view with the end broken away. Fig. 16 is a side View of Fig. 15. Fig. 17 is an end view of Fig. 15. Fig.

Serial No. 177.103. (No model.)

1S is a bottom plan view of Fig. 16. Fig. 19 is a side view of one of the I-beams constituting one of the main elements of the bolster. Fig. 20 is asection of Fig. 19, and Fig. 21 is a top plan view of Fig. 19. Figs. 22, 23, 24, 25, 26, 27, and 28 illustrate the fourth example. `Fig. 22`is a top plan view of one-half of the bolster with a part broken away. Fig. 23 is a side view of Fig. 22. Fig. 24 is an end View of Fig. 22. Fig. 25 is a bottom plan view of Fig. 23. Fig. 26 shows one of the I-beams constituting a part of the bolster with its lower flange and part of its web cut away. Fig. 27 is a cross-section of Fig. 26. Fig. 28 is a bottom plan View of Fig. 26.

. Referring to the several figures, the numeral l designates the rolled flange-beams of I shape and channel shape in cross-section, the first, second, and fourth examples with the webs and portions of the lower fianges out away, as shown in Figs. 3, 10, and 26;

.2, skeleton filling-blocks located between the parallel ends of the rolled anged beams; 3, truss-plates bent to the shape shown in the drawings, so that the en ds will be in a higher plane than the Vcentral portion `o1" a plate when the said plate is in position; 4, trussstools located between the lower anges of the rolled anged beams and the truss-plates and which deepen the truss; 5, top tie-plates; 6, filling blocks located between the rolled flange-beams and above the truss-stools and secured in place by rivets; 7, the lower walls of the skeleton illingblocks; 8, a iiange upon each block oblique to the lower wall; 9, the side walls of the blocks; 10, the end walls; `11, top tie-pieces; 12, seats at the upper surfaces of the blocks for the anges of the rlled beams; 13, the webs of the blocks forstrengthening the same, and 14 designates rivets which unite the ends of the truss-plate to the skeleton tilling pieces or blocks between the ends of the parallel beams.

In Fig. 1 the numeral 15 denotes notches in the ends of the bolsters formed by cutting away portions of the webs and flanges, the skeleton filling-blocks being shaped to conformto the shape of the notches.

The example shown on Sheet 1 is especially adapted for cars having high bodybolsters IOO and the examples on Sheets 2 and 3 for cars with low body-bolsters. The skeleton filling pieces or blocks are made integral and provided with suitable strengthening-Hanges and recesses and with holes for rivets which secure the filling-blocks to the rolled anged beams and the truss-plate.

The first and second examples illustrate the main elements of the bolster comprised of channel-beams, and in the third and fourth examples the main elements are of rolled beams I-shaped in cross-section.

The fourth example has the lower flanges and webs of the I-beams cut away, whereas in the third example the beams have the lower fianges integral, as they are rolled at the mills.

vention, Ido not thereby intend to limit the scope thereof to such examples, inasmuch as modifications and changes may be introduced at the will of the manufacturer. For instance, I may use pressed-steel channel-Y beams for the main elements of the bolster and slightly alter the skeleton filling-blocks to adapt them for the changes in form. Such and other minor changes and modifications I shall regard as falling within the scope of my claims.

What I claim as new, and desire to secure by Letters Patent, is-

l. A truck-bolster comprising two flanged beams arranged in parallel planes and having portions of their lower flanges cut away; a filling-block between the beams; atruss-plate; a truss-stool; and skeleton filling-pieces between the ends of the anged beams; the ends of said truss-plate being riveted to the skeleton filling pieces or blocks.

2. A truck-bolster comprising two flanged beams having portions of their lower anges cut away; a filling-block; a truss-plate; a truss stool; and skeleton filling pieces between the ends of the iianged beams, each filling-piece having an oblique ange as 8 to which the ends of the truss-plate are riveted.

3. The combination in a bolster; of two anged beams arrangedin parallel planes and having portions of their lower anges cut away; a filling-block uniting the beams at their centers; a top tie-plate; a truss-plate; a truss-stool; and skeleton filling-pieces located between the ends of the hanged beams; the ends of the truss-plate being riveted to the lower walls of the skeleton filling-pieces.

beams and to which the ends of the trussplate are secured by rivets.

5. The combination in a truck-bolster, of two channel-beams having portions of their lower flanges removed and also portions of their upper flanges and webs removed; a trussplate; a truss-stool; skeleton filling-pieces located between the ends of the beams and secured in place by rivets; and a top tie-plate;

fthe ends of the truss-plate being secured to While I have illustrated only four exam- Y ples of the physical embodiment of my in-v the skeleton filling-pieces; and the bolster at its top having the notches or recesses l5, in substance as set forth.

6. The combination in av truck-bolster of two flanged beams with flanges facing each other, portions of the lower flanges being cut away; a truss-plate; a truss-stool; and skeleton filling-pieces located between the flanges of the beams and secured in place by rivet-s; the top surfaces of the filling-pieces being provided with seats to receive the fianges of the beams. l

7. The combination in a truck-bolster of two flanged beams arranged in parallel planes; a truss-plate located beneath the parallel flanged beams; a truss-stool between the trussplat-e and theflanged beams; and integral skeleton filling-pieces located between the ends of.' the flanged beams and secured in place by rivets; the ends of the truss-plate being riveted to the lower surfaces of the skeleton filling-pieces.

8. The combination in a truck-bolster of two flan ged beams arranged in parallel planes; a trussplate located beneath the parallel flanged beams; a tr uss-stool between the trussplate and the flanged beams; and skeleton filling-pieces located between the ends of the flanged beams and secured in place by rivets; the ends of the truss-plate being riveted to the lower flanges of the skeleton fillingpieces and to the flanges upon the pieces.

In testimony whereof I affix my signature in presence of two witnesses.
